Technical Field

The invention relates to the technical field of ironmaking discharging equipment, in particular to a jaw type valve control device in an ironmaking discharging system, which is suitable for a hydraulic transmission jaw type valve system with a single hydraulic station room and a valve platform.

Background

The jaw gate is widely applied to material distribution and unloading of materials, when the jaw gate works, a rocker is pushed manually or by an actuating mechanism, a gear drives the fan-shaped gate plates to rotate along an axis, the two fan-shaped gate plates are opened towards two sides, the materials fall immediately, and after the material receiving device is fully loaded, the actuating mechanism drives the rocker to reset the fan-shaped gate plates and close and cut the falling materials. At present, a jaw type valve mostly adopts an electro-hydraulic push rod or full hydraulic transmission, an in-place monitoring device adopts a non-contact proximity switch, the jaw type valve is applied to a metallurgy iron-making discharging system, and due to the fact that the environment is severe, an electrical detection line is easy to damage, the proximity switch is easy to generate misoperation under the action of dust and dirt, the condition that an electro-hydraulic push rod motor does not act or the motor is burnt out due to long-term work often occurs, and the maintenance rate is high. At present, a jaw type valve adopting an electro-hydraulic push rod in an iron-making discharging system accounts for most of the jaw type valves, a motor load circuit and a proximity switch circuit for in-place monitoring are arranged near the valve, the circuit damage and the electrical component damage rate are high, and great resistance is generated to remote control.

The hydraulic jaw gate is widely applied to industries such as building materials, metallurgy, mines, electric power, chemical engineering, light industry, grain and the like, is an unloading control device of various blanking systems, and most of bulk materials are loaded into the feeding field of trains, automobiles, belt conveyors or other receiving devices from a stock bin through the hydraulic jaw gate. The conventional hydraulic jaw gate has the defects of long pushing stroke and installation angle limitation, which cause the operation to be laborious, inflexible in opening and closing, unstable in operation, complex in structure, large in occupied space, complex in operation and the like of most hydraulic jaw gate devices, and has the defects of high power consumption, high failure rate and relatively short service life. The blowing arc plate of traditional jaw gate is external, and it is enough to handle the great material of granule, but when handling dust class material, current jaw gate can produce a large amount of dust when the blowing, pollutes the on-the-spot production environment, is unfavorable for operating personnel's healthy, blocks the gap in the machinery, causes the not smooth of equipment action.

Meanwhile, the hydraulic oil cylinder generally selected also has some disadvantages. First, the efficiency is low because of the large resistance and leakage of the fluid flow. If mishandled, the leak not only contaminates the field, but can also cause fire and explosion accidents. Secondly, since the operation performance is susceptible to temperature variation, it is not suitable to operate under very high or very low temperature conditions. Thirdly, the hydraulic components are more demanding to manufacture precision and therefore more expensive. Furthermore, a strict transmission ratio cannot be obtained due to leakage of the liquid medium and compressibility effects. The reason is not easy to find out when the hydraulic transmission fails, and the use and maintenance also require higher technical level.
